[Live-devel] RTSPclient and DarwinInjector in the same application

[S Mathur]

Hello,

I have modified the openRTSP/playCommon.cpp code such that it
intercepts the M4A-LATM subsession in my streaming session and feeds
it to a decoder filter. The decoder filter feeds data to an encoder
filter which in turns feeds an MPEG4LATMRTPSink.

The subsession related code is as follows...
subsession->sink =  latmSink;
subsession->sink->startPlaying(*aacEncFilter, subsessionAfterPlaying,
subsession);
....

My latmSink is also associated with a DarwinInjector:
injector->addStream(latmSink, audioRTCP);
injector->setDestination(..)


My problem: A get a select() failed error in
BasicTaskScheduler::SingleStep() because  RTCPInstance's destructor
gets invoked prematurely. The ANNOUNCE (of the modified stream named
liveST.sdp) to the Darwin server does goes through successfully.

Here is the transcript, error is at the bottom:

Any suggestions on what I am doing wrong?
